Abstract

Dans au moins un mode de réalisation, l'invention concerne un guide de lumière plan (1) qui présente au moins un moyen de diffusion (5) pour diffuser la lumière, le moyen de diffusion (5) créant un coefficient de découplage. Le coefficient de découplage est réglé variable le long d'une direction principale de guidage de lumière (z). Dans une direction (L) perpendiculaire aux faces principales (2) du guide de lumière plan (1), une valeur d'opacité s'élève au maximum à 0,10, un coefficient de transmission est d'au moins 0,75 et le quotient entre une luminance minimale et une luminance maximale, vu sur l'ensemble d'une zone de rayonnement (A) d'au moins une des faces principales (2), représente au moins 0,75.
